I think the 3ware cards have it too. That's only useful if the drive LEDs are configured to correctly match the port. :) We've had custom built servers with 4 drive bays arrive with the LEDs either not connected, or connected to different ports on the RAID controller than the drives were on. Very confusing until we started double-checking the connections when the servers arrived. -- Freddie Cash, LPIC-2 CCNT CCLP Network Support Technician School District 73 (250) 377-HELP [377-4357] fjwcash+freebsd@gmail.com
